I've noticed for quite a while that some daemons hang around after
exiting a gui. As a test, I took a freshly booted system and ran
'ps -ef'.
I thing started xfce using startx with the following line in .xinitrc:
ck-launch-session dbus-launch --exit-with-session xfce4-session
I took another snapshot of the processes and then exited xfce.
A third process snapshot compared to the first then showed five
processes hanging around:
UID PID PPID TIME CMD
root 1534 1 /usr/sbin/console-kit-daemon --no-daemon
polkitd 1601 1 /usr/lib/polkit-1/polkitd --no-debug
root 1685 1 /usr/libexec/upowerd
bdubbs 1791 1 /usr/bin/pulseaudio --start
bdubbs 1803 1791 /usr/libexec/pulse/gconf-helper
I notice that
/usr/lib/polkit-1/polkit-agent-helper-1
/usr/libexec/dbus-daemon-launch-helper
have the suid bit set so that's probably how the first three get
started, but it's irritating that these don't get shut down upon exit.
I suppose on a multi-seat system you wouldn't want them shut down if
another instance is using them, but shouldn't they be able to figure
this out?
I don't think this is a BLFS specific issue, but does anyone have any
thoughts about this?
